This is why there has been alot done to the design and thread form types and the percentage amount of thread engagement for the cue joint.
I like the fine pitched threads, as they mechanicaly hold the two pieces together tighter for the same torque amount.
As far as movement in the joint, there is no movement untill the load exceedes the friction or the elastic point of what ever is holding it together.
So if the jointed faces are held together with a force of 200 N, if you try pulling it apart with 100 N, nothing will happen.If you apply a force of 250N,the joint will pull apart by the distance that 50N stretches the materials involved.
Most likely, your friend has a cue that they are used to ,and that is his reason for not wanting to change.
